# What types of detectors are supported out of the box? Firewall for AI offers a rich set of pre-built detectors that can identify many different types of sensitive data, including personally identifiable information (PII), payment card industry data (PCI), protected health information (PHI), secrets, and credentials. These detectors are powered by advanced machine learning models and can be easily integrated into your application with just a few lines of code. Refer to our detector glossary at docs.nightfall.ai/docs/detector-glossary for a complete list of available detectors. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
